Packaging Specifications: 20 kg/blue iron drum, 170 kg/blue iron drum. Different specifications meet the needs of different customers. Small specifications are convenient for small enterprises or laboratories to purchase and use in small quantities, while large specifications are suitable for enterprises with large - scale production, which can reduce packaging costs and procurement frequency.
Core Component: Non - silicon component. This enables the product to effectively avoid adverse effects caused by the introduction of silicon elements, such as surface defects and compatibility problems, in some application scenarios with special requirements for silicon elements.
Product Performance and Advantages
Efficient Defoaming: In the application of non - silicon defoaming for polymer - based solvent - free radiation curing wood coatings, industrial coatings, printing inks and binders, it can quickly eliminate the foam generated in the system. For example, in the process of UV - cured ink printing, the rapidly flowing ink is easy to generate a large amount of foam. BYK - 1790 can quickly play a defoaming role to ensure clear printing patterns and uniform colors, and avoid printing quality problems caused by foam.
Wide Applicability: It is suitable for colored and non - colored systems. Whether it is colored industrial coatings (such as automotive topcoats) or transparent wood overprint varnishes, it can stably play a defoaming effect. There is no need to replace the defoamer product due to the color difference of the system, which simplifies the procurement and use process for customers.
No Negative Effects: As a non - silicon defoamer, it has no negative impact on the wettability and gloss of the substrate. During the application of industrial coatings, it will not cause problems such as shrinkage cavities and gloss reduction of the coating due to the addition of defoamers, which helps to maintain the original beauty and performance of the coating and ensure the high - quality appearance of the final product.
Environmental Protection Characteristics: Since it is applied in a solvent - free radiation curing system, it meets the current environmental protection requirements, reduces the emission of volatile organic compounds (VOC), meets the needs of industrial production, responds to environmental protection policies, and helps enterprises achieve green production.
Scope of Application and Scenarios
Main Application Fields
Coating Industry: Solvent - free radiation curing wood coatings, which can be used for surface coating of high - end furniture and wood floors to improve the appearance quality of products; Industrial coatings, such as automotive parts coating and metal protection coating, ensure coating quality and performance.
Printing Industry: Printing inks, especially UV and EB - cured inks, are suitable for packaging printing (such as food packaging and pharmaceutical packaging printing) and label printing to ensure exquisite printing effects.
Adhesive Industry: Polymer - based adhesives, in scenarios such as electronic device assembly and wood bonding, help eliminate foam during production and improve bonding quality.
Typical Application Scenarios
High - end Furniture Coating: In the UV curing varnish coating process of solid wood furniture, the use of BYK - 1790 can avoid foam generation, so that the furniture surface forms a smooth and high - gloss paint film, improving the grade and market competitiveness of furniture.
Food Packaging Printing: In the UV ink printing process of food packaging, the defoamer can ensure the clarity of printed patterns and uniform adhesion of ink, and meet the safety requirements of food contact materials at the same time to ensure food safety.
Usage and Storage Recommendations
Adding Method: The recommended dosage is 0.1% - 0.5% of the total formula amount. It can be directly added during the stirring process of coating, ink or adhesive production, and stir thoroughly to ensure uniform dispersion of the defoamer and achieve the best defoaming effect. If the system viscosity is high, the defoamer can be diluted with an appropriate amount of system solvent before adding.
Compatibility Test: When using for the first time or changing to a new raw material system, a small - scale test is required to verify the compatibility of BYK - 1790 with other components in the system (such as resins, pigments, additives, etc.), and observe whether phenomena such as turbidity, flocculation, and delamination occur, as well as the impact on product performance such as curing speed and hardness.
Storage Conditions: It should be stored in a cool and dry place, with the temperature controlled at 5 - 35℃, avoiding direct sunlight, high temperature and freezing. After opening, it should be sealed and stored to prevent the product from getting damp, oxidized or mixed with impurities. The shelf life of unopened products is usually 12 months.
